3 Claims. (Cl. 81-3) This invention relates to a bushing-inserting tool and more particularly to a wrench for inserting washers or bushings in relatively inaccessible places.

It is an object of the present invention to provide a simple and eflicient tool for placing parts in places which are relatively inaccessible.

In accordance with one embodiment of the invention, a tool having a relatively long handle has fixed to one end thereof a block having an aperture extending therethrough which conforms to the shape of the part to be handled. This block has a slot formed in it which intersects the aperture and in which a substantially U-shaped spring is flexibly positioned whereby a part which has been passed part way through the aperture may be pushed back between the legs of the springand held in the slot. A post or bolt-receiving slot is formed transversely on the part-receiving slot whereby a part held in the tool by means of the spring may be engaged on a post or shaft and then stripped from the grip of the spring and back into the aperture whereby the tool may either be lifted from the part and the part permitted to remain upon the shaft or stud in the desired position or the tool may be manipulated to thread the part onto the bolt.

A better understanding of the invention may be had by reference to the following detailed description when considered in conjunction with the accompanying drawings wherein:

Fig. 1 is a plan view of a tool made in accordance with the present invention;

Fig. 2 is a side elevation of the tool shown in Fig. 1;

Fig. 3 is an enlarged fragmentary view of the partreceiving end of the tool partly in section and showing a part being inserted into the tool;

Fig. 4 is a View similar to Fig. 3 but showing the part resiliently held by the spring;

Fig. 5 is a transverse sectional view taken along the line 5-5 of Fig. 3 in the direction of the arrows;

Fig. 6 is a fragmentary sectional view taken along the line 6-6 of Fig. 3 in the direction of the arrows, and

Fig. 7 is a sectional view taken on the line 7--7 of i Fig. 4 in the direction of the arrows.

bushing, nut or washer which is to be handled by the tool.

In cutting the slot an upper plate 18 and a lower plate 19 are formed which will receive between them the tongue 14, and the block 16 may be attached to the projectio-n 12 by means of rivets extending through the plates 18 and 19 and the tongue 14 thus tosecurely. attach the block 16 to the projection '12. After the block 16 has been thus fixed to the projection 12, a substantially U-shaped spring may be placedin theXslot 15 and.

' fixed in the position shown by means of'a pair Of'PiIlS 26..

In the drawings the handle 11 of the tool as indicated in Figs. 1 and 2 may be of any desired length, the handle being broken to illustrate this feature. At its left end (Figs. 1 and 2) the handle 11 has mounted on it a projection 12 which may be welded, brazed or soldered to the handle 11 as indicated at 13. The projection 12 has a tongue 14 formed on it which extends into a slot 15 formed in a block 16 whereby upon inserting the tongue 14 into the slot 15 the right ends (Figs. 3, 4, 5 and 6) of the block 16 will engage shoulders 21 on the projection 12. The slot 15 extends completely across the block 16 from top to bottom as viewed in Figs. 3 and 4 and extends to the middle of an aperture 17 formed in the block 16 transversely of the slot 15. The aperture 17 extends completely through the block 16 from top to bot tom, as shown in Fig. 5, and conforms to the shape of a The pins 26 will hold the spring 25 in the position shown where the legs 27 thereof, which are bent outwardly at their ends, may receive a bushing 28 which is shown in the present embodiment as hexagonal and provided with a central aperture 29. Thus the plates 18 and 19 in cooperation with the spring 25 form a socket for receiving the bushing and resiliently holding it. A longitudinally extending slot 30 of a width somewhat greater than the diameter of the aperture 29 in the bushing is formed in the plates 18 and 19 and extends from a point adjacent the right ends of the plates 18 and 19 to a point where it intersects the aperture 17.

From the foregoing it is believed to be apparent that a bushing or washer 28 may be manually placed in the position as shown in Fig. 3 by passing it part way through the aperture 17 and then moving it back to the position shown in Pig. 4 by forcing it past the rounded ends of the legs 27 of the spring 25 where it will be resiliently held by the spring while the tool is manipulated to move the bushing 28 into position where a stud or bolt or shaft may be received within the central aperture 29 of the bushing, and then simply by pulling the tool away from r the shaft or stud, the bushing will move back to the position shown in Fig. 3 and will drop down out of the aperture 17 as soon [as it is released by the plates 18 and 19 and the spring 25 whereupon the tool may be retracted.

While the tool has been described in connection with the handling of a bushing it is obvious that it may serve as a wrench for inserting a nut into a relatively inaccessible place and may then be used to thread the nut onto a threaded stud or bolt.

Although a specific embodiment of the invention has been described herein, it will be understood that modifications thereof may be made without departing from the scope and function of the invention.

What is claimed is:

1. A tool for placing bushings or the like in relatively inaccessible locations comprising a handle, a pair of spaced plates at one end of said handle for receiving a bushing between them, and resilient means positioned between said plates for holding such bushing between the plates, said tool having a passage communicating with the space between said plates through which a bushing may be passed to position it in engagement with the resilient means and another passage communicating with the first passage whereby a post may be entered into a bushing to strip such bushing from the tool.

2. A tool for assembling bushings or the like on studs or shafts comprising a handle, a block fixed to the handle and having an aperture extending therethrough, the walls of which conform substantially to the configuration of a bushing to be handled by the tool, said block having a slot extending from approximately the middle of the aperture an appreciable distance toward the handle of the tool, said slot having its medial plane normal to the walls of the aperture to form upper and lower plates, and a substantially U-shaped spring fixed in said slot with the legs thereof extending toward the aperture for retaining between them a bushing which has been passed part way through said aperture and then forced toward the handle Patented Apr. 8, 1958,

6 ml of the tool between the legs of the U-shaped spring, each of said plates having a second slot formed transversely of the first slot and extending from a point adjacent said handle to intersect the aperture, said second slots providing stud-guiding walls for guiding a stud or shaft into a central aperture in a bushing held between the legs of the spring.

3. In a tool for assembling bushings or like parts on studs or shafts and including a handle, an improved part-holding means which comprises a pair of rigid, cooperating plates a'fiixed to 'oneend of the handle and spaced a distance sufficient to receive such a part between 7 them, and spaced spring means positioned between the plates for resiliently gripping surfaces of such part Which are normal to said plates when such part is between said plates, at least one of said plates having an aperture therethrough which conforms substantially to the configuration of said surfaces to guide such part to the space between the plates.
